DRIVING MECHANISM.

Specification of Letters Patent.

Patented May '7, 1918.

Application filed. July 29, 1916. erial No. 111,987.

To all whom it may concern:

Be it known that 1, LEON G. ADAMS, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Driving Mechanism, of which the following is a specification.

This invention relates to reversible driving mechanisms adapted for use for driving any machine or driven mechanism, such for instance as laundry machines, though it will be understood that its use is not restricted to that purpose.

The object of the invention is to provide a driving mechanism for driving any machine or driven device continuously in one direction, or alternately in opposite directions at the option of the operator, the re verse being efiected automatically by means driven by the driving mechanism.

Other ob ects will appear from the following description, reference being made to the accompanying drawing, in which I have illustrated a preferred embodiment of the invention, and in which Figure 1 is a plan view of my improved driving mechanism.

Fig. 2 is a side elevation.

Fig. 3-is an end elevation, a part of the gearing being shown diagrammatically.

Fig. at is a View of the opposite end of the gearing from that illustrated in Fig. 3, the gear wheels in this view being shown diagrammatically.

Fig. 5 is a cross sectional view on the line 55 of Fig. 1.

Fig. 6 is a cross sectional view on the line b 66 of Fig. 1.

The entire driving mechanism in the embodiment in which I have illustrated my invention is supported by a base 1 adapted to be mounted in any fixed position in relation to the driven mechanism. The drive mechanism includes a drive shaft 2 journaled in bearings 3 and provided with a pulley 4 whereby the drive shaft may be driven from a motor or engine. A gear wheel 5 is attached to the drive shaft and meshes with a similar gear wheel 6 which is attached to a shaft 7, the latter being journaled in bearings 8 upon the base 1. The shaft 7 is parallel with the shaft 2 and is maintained in constant rotation by the gear wheels 5 and 6 when the shaft 2 is in operation.

A pinion 9 is loose upon the drive shaft 2 and is in constant mesh with a gear 10 in and constituting a part of the driven mechanism. By this arrangement the gear 10, which may be referred to as the driven mechanism, will be operated by the pinion 9 when the latter is clutched or made fast upon the shaft 2, but when the pinion 9 is loose upon the shaft 2 the driven mechanism 10 will not be operated by said pinion 9. A pinion 11, similar to the pinion 9, is loose upon the shaft 7 and is also in constant mesh with the gear 10 so that said gear 10 will be operated by the pinion 11 when the latter is clutched or made fast upon the shaft 7 but when the pinion 11 is loose upon the shaft 7 the driven mechanism 10 will not be operated by the pinion 11. Thus, the driven mechanism may be operated by the pinion 9 or the pinion 11 and, since the pin ion 11 rotates in a reverse direction from the pinion 9, it will be understood that the driven mechanism will also be operated by the pinion 11 in a reverse direction from that in which said driven mechanism is 0perated by the pinion 9.

As'first suggested in this specification, my improved driving mechanism is specially adapted for use in operating washing machines and other mechanisms where it is desired to operate the driven mechanism, that is to say, the mangle or washing mechanism of a washing machine alternately in reverse directions. For effecting this reverse operation, my improved driving mechanism is equipped with clutch devices for alternately clutching the pinions 11 upon their respective shafts, so that the gear 10 is alternately driven by the pinions 9 and 11 and is therefore alternately operated in opposite directions.

The clutch mechanism for the pinion 9 includes a clutch member 12 rigid with said pinion and a sliding clutch member 13 keyed to slide upon the shaft 2 and tojengage with the clutch member 12 in order to clutch or make fast the pinion 9 upon the drive shaft 2. The clutch mechanism for the pinion 11 includes a clutch member 14 rigid with said pinion and a coiiperating clutch member 15 keyed to slide upon the shaft 7 and arranged to engage with the clutch member 14: to clutch or. make fast the pinion 11 upon the shaft 7. A connecting actuating lever is provided which engages both of the sliding clutch members 13 and 15 and is operative to move said clutch members alternately into and out of engagement with their ooperating clutch members, or to retain both of said clutch members 13 and 15 out of engagement with their co5perating clutch members to permit the driven mechanism to remain idle or stationary while the driving mechanism is in operation. The clutch shift lever mentioned comprises an upper portion 16 and a lower portion 17, both pivoted upon an axis 18 midway between the shafts 2 and 7. The two members 16 and 17 of the clutch shift lever, as will be understood by reference to Fig. 5, are in the form of yokes which embrace the clutch members 13 and 15. The shift lever thus formed is pivotally connected to blocks or shoes 19 seated in an annular groove 20 in the clutch member 13, so that by oscillation of the clutch lever the clutch member 13 may be moved into and out of engagement with the clutch member 12. The lever is also pivotally connected to blocks or shoes 21 seated in an annular groove 22 in the clutch member 15, so that the clutch members 13 and 15 are moved in opposite directions alternately into and out of engagement with their cobperative clutch members by operation of the clutch shift lever.

Movementof the clutch shift lever for i the purposes mentioned is automatically effected. by mechanism driven by the drive shaft. Said mechanism includes a reciprocating plate 23 operating in guides 24 preferably between rollers 25 arranged above and below the. plate. Said plate is provided with a recess 26 on one side having a shoulder 27 at the upper portion thereof and a shoulder 28 at the lower portion thereof. A worm gear 29 is rigid upon the drive shaft 2 and meshes with a gear 30 supported by an axial member 31 journaled in bearings in a support 32 carried by the base 1'. A lug 33 on the gear 30 extends into the recess 26 and alternately engages the shoulders 27 and 28 and thereby shifts the plate 23 in opposite directions. This will beunderstood by reference to Fig. 2, the

' gear 30 revolving in the direction of the arrow 34, and the lug 33 being in engagement with the shoulder 27. The parts, being in the positions shown, the plate 23 will be moved by the lug 33 until said lug traveling in the arc of a circle passes below the shoulder 27 into the larger portion of the recess 26,

thus leaving the plate 23 stationary while the gear 30 continues to revolve. The lug 33. is thereafter engaged with the shoulder 28 and the plate 33 is'thereby actuated in the opposite direction, this reverse move ment of the plate 23 being continuous while the driving mechanism is in operation.

The connection between the plate 23 and the clutch shift lever includes a pivoted element 35 carried by the plate 23 and having a recess 36 which receives a projection 37 on one end. of the clutch shift lever. I Thus,

the clutch shift lever is oscillated by the plate 23 and the clutch members 13 and 15 are moved alternately into and out of engagement with their coiiperating clutch members.

On some occasions it may be desired to operate the driven mechanism continuously in one direction and this is efiected by preventing operation of the clutch members 13 and 15, leaving either of said clutch members in clutching engagement with its cooperating member. In order to prevent operation of the clutch shift lever, I provide means for disconnecting the member 35 from the projection 37. The means last mentioned includes a sliding support 38 and a lever 39 for operating the same. The lever 39 is pivoted at 40 and has pin-in-slot connection 41 with the support 38. Ob-

viously, by operating the lever 39 to raise the support 38, the member 35 will be disengaged from the projection 37 and said member 35 will be carried back and forth without operating the clutch shift lever, thus leaving either of the clutch members 13 or 15 in clutching engagement. The lever 39 is provided with a ratchet member 42 arranged to coperate with a notched seg ment 43 of usual construction in order to hold the lever 39 in any selected position. By placing the ratchet 42 in the notch of the segment either clutch member may be left in engagement, but by depressing the lever 39 until the ratchet 42 engages in the notch 45, both clutches will be automatically disconnected. In order to effect disengagement of both clutches and to retain them disconnected, the support 38 is providedwith two cam'shoulders 46 arranged to engage an extension 47 (Fig. 5) on the lower part of the clutch shift lever and thereby move the clutch shift lever to a positionin which both clutch members 13 and 15- are out of engagement with their coiiperating clutch members.

In order to hold the clutch shift lever in its two positions for retaining either clutch member 13 or 15 in engagement, a special retaining device is provided. The retaining device includes a lever 48 pivoted upon a support 49 and having a notch 50' in its lower end embracing one end of the clutch shift lever. The lever 48 has an ar'euate slot 51 through which a projection 52 extends. A bracket 53 is attached to the lever 48 and guides a latch device 54 having its lower end somewhat pointed, as indieated'at 55, (Fig.2), so that the oblique wa1ls1leading to the point operate against the projec tion 52. A projection 56 on the latch mem ber 54 is encircled by a spring 57 which actuates the latch member downwardly and, by causing it to cotiperate with-the projec tion 52, is effective to-hold the lever '48 in either of its two lateral positions and is thereby effective to hold the clutch shift lever in position to hold either of the clutch members 13 or 15 in or out of engagement.

It will be understood that the construction and combination of these parts may be varied Without departure from the principles of the invention, and that I do not limit myself to unessential details.
